[Pneumococcal infectious endocarditis in an infant (case report)].

In a 10-month-old infant with purulent pneumococcal meningitis without structural heart disease acute infectious endocarditis developed. Echocardiographic examination revealed vegetations on both cusps of the mitral valve. With regard to the age and critical condition of the infant, in the acute stage surgical removal of the vegetations, was not indicated. During long-term intravenous antibiotic therapy the vegetations on the mitral valve and clinical and laboratory manifestations of endocarditis disappeared. The valve was, however, devastated and the child developed severe mitral insufficiency. Because of progressive cardiac failure which could not be controlled by drugs, at the age of 19 months a plastic operation of the mitral valve had to be performed after which the haemodynamics and clinical condition improved markedly.

[Infectious endocarditis: its resistance to therapy, causative factors and means of combating it].

Based on the data obtained during observation over 270 patients with infectious endocarditis the authors discuss factors that cause antibacterial therapy resistance encountered particularly often over the recent decade. Among the factors, the authors mark polyetiology of the disease over the recent years, "new" patterns of endocarditis in terms of the pathogenesis, predominance of primary endocarditis with highly virulent microorganisms, late disease diagnosis, inadequate antibacterial treatment, and so forth. Approaches to overcoming treatment resistance are also considered.

[Parallels in clinical, laboratory and instrumental data between systemic lupus erythematosus and infectious endocarditis in children].

The aim of the study was the comparison of clinical, laboratory end instrumental data between systemic lupus erythematosus (SLE) end infectious endocarditis (IE) for analysis of similar and different features. Clinical, laboratory and instrumental data were analysed and compared for 96 SLE and 23 IE patients. SLE and IE have the following common features: fever, pleurisy, pericarditis, myocarditis hemorrhagic vasculitis, renal disorders, anaemia, concentrations of circulating immune complex (CIC), IgM. Characteristic of SLE were skin erythema, alopecia, cerebrovasculitis, lymhadenopathy, pneumonitis, frequent articular lesions, pancytopenia, high IgG levels, and antibodies to DNA. After echocardiographic investigations a rare revelation of the damage of endocardium, and the lack of destruction of the valve were detected. IE was characterized by thromboembolic complications, splenomegaly, pneumonia, high IgM levels, high incidence rate of RF, positive hemoculture. By echocardiographic studies bacterial vegetations end valvular pathology were detected. These data gives us the possibility for early differential diagnostics of these two diseases.

[Indications and surgical techniques in the acute phase of infective endocarditis].

Infectious endocarditis is increasingly resistant to antibiotic therapy, due to the increasing number of patient with cardiovascular prostheses or those who are severely immunosuppressed. Frequently, this syndrome and its complications can only be solved with surgery. In this article, which is based on the international literature plus own observations in 77 patients, the indications for surgery and the different technical approaches during the acute phase of infectious endocarditis are reviewed. Surgery to control infectious endocarditis is indicated when there is one of the following situations: a) persistence of infection despite an adequate antibiotic treatment, usually due to a specific pathogen (Staphylococcus aureus, fungus, etc.) or to a low antibiotic penetration into the infected issues (abscess); b) progressive hemodynamic deterioration due to tissular destruction and development of valvular incompetence or fistulous communications or c) development of other complications (repetitive embolism, cardiovascular aneurysms, conduction blocks, etc.). Hemodynamic deterioration due to heart failure refractory to medical treatment is the most frequent indication for cardiovascular surgery, and this was present in 61% of our patients. The timing for surgery is still controversial, although scheduling it at an early stage is generally preferred. The specific surgical technique is chosen according to the degree of tissular destruction and is aimed to remove the infected tissue and to repair the damaged structures or, if this is not feasible, to implant cardiovascular prosthesis.

[Neurologic manifestations of infectious endocarditis].

Thirty out of 287 patients (10.4%) admitted to hospital for infective endocarditis between December 1970 and January 1990 had neurological complications. Twenty-three patients had native valve infectious endocarditis and 7 had prosthetic valve endocarditis. The clinical features were characterized by the frequency of aortic valve involvement (23 out of 30) and other complications, especially cardiac failure (16 cases) and peripheral vascular manifestations (7 cases). The commonest organism was the staphylococcus (53% of identified organisms) but the number of negative blood cultures was high (50% of cases). The neurological complication was often the presenting symptom of the endocarditis (19 cases) but it occurred after bacteriological cure in 4 cases. The complications observed were cerebral ischemia (16 cases), cerebral haemorrhage (11 cases), coma (2 cases), and one peripheral neuropathy causing a Claude Bernard Horner syndrome. These complications presented with hemiplegia in 17 cases, a meningeal syndrome in 8 cases, a convulsion in 1 case, a Von Wallenberg syndrome in 1 case, and a Claude Bernard Horner syndrome in 1 case. Twelve patients had a transient or permanent neurological coma. Cerebral CT scan showed ischemic lesions in 7 cases and haemorrhagic lesions in 10 cases. Carotid angiography demonstrated mycotic aneurysms in 6 patients. Twelve patients died: the cause of death was neurological coma (7 cases), low cardiac output (4 cases) and haemorrhagic shock (1 case). Four patients underwent neurosurgery: 3 for clipping a mycotic aneurysm and 1 for drainage of an intracerebral haematoma. Poor prognostic factors were: coma, cardiac failure, cardiac valve prosthesis and, above all, the extent and multiplicity of the neurological lesions. The authors propose the following measures to improve the prognosis: early surgery in cases of large and/or mobile vegetations especially when the infecting organism is a staphylococcus and when a systemic embolism has occurred; routine CT scanning and/or digitised cerebral angiography in all patients with infective endocarditis to detect surgically accessible mycotic aneurysms.

[Infectious endocarditis. Analysis of 20 death cases in Santa Casa de São Paulo].

PURPOSE: To analyze the clinical, laboratory and pathological aspects of 20 cases of infectious endocarditis (IE) who died. The authors compared patients with diagnosis before death of IE and those with diagnosis was made after autopsy. METHODS: Twenty patients who died with IE between April 1982 and November 1991 were studied. We looked for the clinical aspects (fever, cardiac murmurs, anemia, splenomegaly, embolic events and skin manifestation), laboratory aspects (hemocultures), echocardiographic and anatomopathologic features (valvar vegetations events and embolic accidents founded at autopsy). The sample was divided in two sub-groups: A--with clinical diagnosis of IE before and B--without diagnosis before death. RESULTS: Group A--9 patients aged 8-58 years, 3 men, all them with cardiac murmurs, fever and anemia, 5 with splenomegaly. Hemocultures were done in 7 patients and positive in 1. Echocardiogram with valvar vegetation were found in 4 out of 5 patients (80% positive). At autopsy mitral valve vegetation were present in 7, aortic 3, tricuspid 3. One patient showed the exposure of three valves and two of 2 valves. Embolic events were found in 4. Group B--11 patients most of them older then 50 years (54.5%) (p < 0.05) 5 men, all them presented fever and anemia. Cardiac murmurs in 6 (54%) and none with splenomegaly. In one case hemoculture and echocardiogram, were done and were negative. Anatopathologic study showed compromise of mitral valve in 5, aortic 4, tricuspid 2, pulmonary 1. Two patients had 2 valves compromised. In one case a mural vegetation (right atrium) was found. Embolic events were present in 2 cases. CONCLUSION: In group B a significant number of patients (p < 0.05) were older than 50 years and presented his symptoms as an acute illness. We concluded that older patients with compromised general state and fever with or without embolic events IE must be remember.

[Tricuspid valve replacement for infectious endocarditis associated with ventricular septal defect--report of three cases].

We reported two male and one female patient (17, 36 and 47 years old, respectively) who presented infectious endocarditis (IE) in association with ventricular septal defect (VSD). In all cases, surgical treatment was performed in the acute stage of IE for persistent sepsis, pulmonary embolisms, and for giant vegetations. Because the tricuspid valve apparatus was severely damaged, valve replacement with the Carpentier-Edwards pericardial bioprosthesis was done and small VSD was directly closed in all cases. In one case, a complete heart block occurred, which necessitated postoperative implantation of a permanent pacemaker. All patients recovered and resumed their original social activities without the relapse of endocarditis.

[Q fever infectious endocarditis. 3 cases].

An acute infectious disease with predominant pulmonary symptoms, Q fever, may become chronic as hepatitis or, more frequently, endocarditis. We report 3 cases of Q fever endocarditis. In 2 of these patients endocarditis developed on cardiac valve prosthesis. The 3 patients have been under doxycycline for more than a year, and their condition is satisfactory. A review of the literature provides additional data on the epidemiological, aetiological, clinical, biological and therapeutic aspects of this rare type of endocarditis. It is recommended to look for chronic Q fever in all cases of endocarditis with negative blood cultures.

[Infectious endocarditis as a complication of cardiac pacemakers requiring emergency removal of the stimulating electrode].

Case report describes a patient with permanent pacemaker (implanted in childhood) who has developed infectious endocarditis with bacterial vegetation on the stimulation electrode while no febrile condition occurred and laboratory tests showed no inflammation. The course of the disease was affected by the previous inappropriate outpatient treatment of an infection in the suture after the pacemaker exchange. It should be noted that echocardiographic examination was essential for both the diagnostics and the choice of strategy. The therapeutic approach consisted of the combination of long-term antibiotic therapy and the explantation of the infected stimulation system. As it was not possible to accomplish by endovasal methods only, cardiosurgery for extraction of the lead was chosen.

[Value of echocardiography in infectious endocarditis].

Echocardiography occupies a fundamental position in infective endocarditis. It is indispensable for diagnosis, prognostic evaluation, appreciation of embolic risk, and surveillance of treatment for patients affected with infectious endocarditis, as well as during the peroperative period. This update recalls the principle data in the literature illustrating the significance of echocardiography in this pathology.

[Surgical treatment of infectious endocarditis complicated by discrete subaortic stenosis: report of a case].

A 39-year-old male with a history of cardiac murmur from early childhood was diagnosed as having infectious endocarditis (IE) complicated by discrete subaortic stenosis (DSS). Echocardiography revealed severe aortic regurgitation, subaortic membranous structure and mild mitral regurgitation. The pressure gradient across the subaortic stenosis was 105 mmHg according to continuous Doppler wave ultrasonography. Aortic valve replacement and resection of subaortic membranous tissue and mitral annuloplasty were performed. Postoperative cardiac catheterization demonstrated that the hemodynamic data were remarkably improved, and the patient was free of symptoms. He is currently well at 6 months after the operation.

Infectious endocarditis and sudden unexpected death: incidence and morphology of lesions in intravenous addicts and non-drug abusers.

BACKGROUND: Intravenous drug (IVD) use is a wellknown risk factor for infectious endocarditis (IE), but there are few morphologic and epidemiologic data comparing IVD-related and non-IVD-related IE in cases of sudden death. MATERIAL AND RESULTS: Between 1992 and 1994, acute IE was diagnosed in 13 IVD users at the Office of the Chief Medical Examiner in Maryland, indicating a yearly incidence of IE-related sudden unexpected deaths of 12 per 100,000. Eleven (85%) cases of acute IE occurred on apparently previously normal valves, and there was one unicuspid valve and one infected porcine prosthesis. There were three right-sided (tricuspid) lesions (23%), nine left-sided lesions (69%), and one multivalvular lesion (8%). During the same period, there were five cases of healed IE in IVD abusers, three of which involved the tricuspid valve. The prevalence of incidental healed lesions in autopsies of IVD users was 0.2%. The healed tricuspid lesions consisted of smooth-edged defects in the valve leaflet without perforations characteristic of mitral or aortic IE. The mean age of the deceased with healed lesions was 45 +/- 6 years versus 34 +/- 10 years for those with acute endocarditis (p = 0.03). During the same time period, there were six cases of acute IE among non-drug users, indicating a yearly incidence of sudden unexpected death of 0.04 per 100,000. Acute IE occurred on congenitally malformed (n = 5) or prosthetic (n = 1) valves. There were two cases of incidental healed IE (mitral and aortic valves), indicating a prevalence of 0.02%. CONCLUSION: IVD users are 300 times more likely to die suddenly with IE than non-IVD users, and healed lesions are 25 times more common. Healed IE of the tricuspid valve is associated with IVD abuse, and has a characteristic gross appearance that differs from healed left-sided IE.

[Fatal infectious endocarditis in a patient with annulo-aortic ectasia and predominant bicuspid valve aortic stenosis. Anatomoclinical case].

A 25 year old female with bicuspid aortic valve and aortic stenosis developed infectious endocarditis due to beta hemolytic streptococcus. Specific antibiotic therapy was not successful, the patient developed multiple embolic episodes and platelet dysfunction that prevented surgery. The patient died 5 weeks after admission. Necropsy showed aortic annulo-ectasia, cystic medial necrosis and localized dissection of the proximal aorta. There were multiple aortic valve vegetations and evidence of inflammatory myocardial involvement, coronary embolization and myocardial infarction. Aortic annulo-ectasia should be investigated in patients with aortic valve endocarditis and early surgery would be advised to prevent aortic dissection.

[Diagnostic value of transesophageal echocardiography in the diagnosis of infectious endocarditis. A comparative analysis comparing it with transthoracic echocardiography].

The aim of this study is to compare the performance of Transesophageal Echocardiography (TEE) and the Transthoracic approach (TTE) in the diagnosis of Infectious Endocarditis (IE). Between October/90, the data we started transesophageal ultrasound, till April/92, we performed 33 TTE in inpatients with clinical suspicion of IE. Twenty pts (61%) had one or two prosthesis. All the pts had a previous TTE. The diagnosis of IE determined by non-echocardiographic data was established on 18 pts. The other 15 pts, without clinical criteria of IE, were used as the control group. The Echocardiographic criteria for the diagnosis of IE were for both diagnostic tools the presence of masses suggesting vegetation of abscess. The diagnosis was correctly made by TTE in 8 of the 18 pts (S-44%) and by TEE in 16 of the 18 pts (S-89%) with clinical criteria for IE. Of the 15 patients without clinical criteria for IE 14 were correctly identified by TTE (Sp-93%) and 13 by TEE (Sp-89%). With a similar VPP (89%) for both tools has TEE a significative higher value for NPV than TTE (87% vs 58%). This study suggests that TEE, at a same level of specificity as TTE, is highly more sensitive in the diagnosis of IE (S-89 14 for TEE and S-44 23 for TTE) a figure that recommends that all patients with clinical suspicion of IE and a negative TTE should perform a TEE.

Freestyle stentless bioprosthesis for active aortic infectious endocarditis with undetermined causative organism.

A 52-year-old woman developed congestive heart failure and was diagnosed with aortic regurgitation with approximately 20 mm of vegetation located on the noncoronary cusp of the aortic valve. The patient had undergone tooth extraction 3 months earlier, and various antibiotics had been given in the treatment of refractory high fever for 1 month. The damage to the aortic valve extended to the fibrous trigone near the mitral valve, and aggressive debridement of necrotic and infected tissue was done. The excised defect was repaired and reinforced with a pericardial patch, and the Freestyle stentless bioprosthesis was implanted using the full-root technique. Although the causative organism was never isolated, recurrent endocarditis has not occurred during 3 years of follow-up. The Freestyle stentless bioprosthesis was useful in the management of active aortic infectious endocarditis with undetermined causative organism for the prevention of recurrent endocarditis in the early postoperative period.

[Selective embolization of ruptured mycotic aneurysm of the duodeno-pancreatic arcade disclosing infectious endocarditis].

The authors report a case of rupture of a mycotic aneurysm of the duodenal pancreatic arcade in a 68 year old man presenting with shock, abdominal pain and rigidity, complicating a case of infectious endocarditis. Emergency treatment consisted of selective embolisation with a coil. This treatment, proposed in view of the clinical condition of the patient and the anatomical particularity of the regional arterial vascularisation, may be a valuable alternative to classical surgery in this type of pathology.

[Etiopathogenetic, clinical and therapeutic findings on infectious endocarditis in drug addicts].

Within the sphere of the infectious pathology one usually finds among drug addicts using intravenous methods, a prominent place is occupied by Endocarditis, a serious complication which is one of the more common causes of death among drug addicts. On the basis of the recent literature and their personal experience, the Authors report on several aspects of this illness in addicts, describing the etiological profile and the clinical manifestations in particular, which show clear dissimilarities when compared with infectious endocarditis in patients who are not addicts.
